GT4 Rear Lower Arm Mount Aluminium 7pcs GT009 for TRAXXAS by GPM  [GT009]

Aftermarket rear lower arm mount for GT4

This aluminium rear lower suspension mount is an aftermarket replacement made for the TRAXXAS 4WD GT4 TEC 2.0 platform and supplied by GPM with model code GT009. It targets hinge pin play by pairing a 6061 T6 aluminium main body with a POM insert to keep the rear lower arm tracking true under load, helping with consistent throttle and corner response.

The main mount is manufactured from a high-tensile aluminium alloy to limit flex, while the POM insert offers measured compliance and closes the gap at the hinge pin. The upgrade focuses on repeatable behaviour rather than aggressive geometry changes, so handling feel becomes more predictable without altering ride height.

Fitment is straightforward as a direct swap for the stock rear lower mount on the stated chassis. Secure the part using the supplied stainless flat head screws and follow your usual rear suspension removal and refit procedure. After assembly, confirm the hinge pin runs freely and verify screw torque after an initial short run.

The package supplies the small fasteners sized to match the original fixings so no extra hardware is normally required. Setup reminders: make sure the POM insert accepts the hinge pin without binding, avoid excessive screw torque, and check neighbouring suspension parts for any contact before full-speed use.
